5The activities of microbes were restrained by acid rain. The number of microorganism in No.

三门江林地土壤微生物的数量均比长塘样地高，在微生物活动旺盛的春季，还高出一个数量级。

Scene forest is in the majority in the total greenbelt area, while the appertain greenbelt and residence greenbelt occupy utterly predominance by the proportion of each type patch accounts for the total number of patch.

本文主要结论：(1)绿地景观类型构成分布不均匀，从各类型占绿地总面积的比例来看，风景林地占有较高的比例，从各类型绿地斑块占总斑块数量的比例来看，附属绿地和居住绿地占有较大的比重。

In the dry land and garden plot, the soil eroding amount of terraced fields is only 1/3 of that be ploughed directly along the slope. It is difficult that assart along the contour in the dry land and garden plot, after the first 1~2 years, the soil eroding amount will increase at double. From the soil and water conservation point of view, the mode that integrates arbor, shrub and grass in woodland is the best, the mode that plants grass in bare land is the second.

等高作梯的旱耕地和园地土壤侵蚀量仅为顺坡直耕的早耕地和园地顺坡的1/3左右；早耕地、园地等高开垦的强度大，开垦之后1~2年土壤侵蚀量成倍增长；从水土保持角度看，林地乔、灌、草结合模式最好，裸地植草模式次之。

The analyses of soil samples indicate that there are high values of physical clay fraction in arbor-bush-grass complex forest and apple orchard, which means strong capability to resist soil wind erosion.

3不同农地表层土壤机械组成分析表明，乔灌草地和苹果园地表层土壤物理性粘粒含量含量较高，说明其抗风蚀能力较强；葡萄园地和灌木林地表层土壤物理性粘粒含量较低，说明其抗风蚀能力较弱。

The preliminary results showed that the atmosphere contaminator mainly contained SO\-2, NO\-\%x\% and suspended granule. Which caused large area acid rain with high frequency. As pollution became more serious, there were decreases in pH value and increases in the content of SO\+\{2-\}\-4 and Al\+\{3+\} in forest soil; the chlorophyll concentration also would decrease...

初步结果表明：大气污染引起珠江三角洲地区发生大面积、高频率的酸雨，主要的污染物有SO2 、NOx、悬浮颗粒物等；随着污染程度的增大，森林土壤pH值降低，SO2 - 4和Al3+质量浓度增大；马尾松、湿地松叶片叶绿素含量降低，生长衰退甚至死亡；但不同树种对大气污染敏感程度不同，种植马占相思比马尾松更能增加林地对酸雨缓冲力和提高土壤肥力。

Items to be declared mainly concentrated in the area of people's livelihood, there are: Xixi Wetland 3 30,000,000 yuan, Chun'an Qiandaohu Town, Tonglu Fuchunjiang town Yaolin town sewage treatment works 13,000,000 Yuan, Lin Hong Gao Zhen, Wang farm town sewage pipe network project 1.90 million in drinking water projects in Lin'an City, 5.55 million yuan, Lin'an City, Changhua hickory woodland soil erosion control works 2,320,000 yuan, rural marsh gas project Chun'an County 1710000 element.

杭州申报的项目主要集中在民生领域，主要有：西溪湿地三期3000万元，淳安千岛湖镇、桐庐富春江镇、瑶琳镇污水处理工程1300万元，临安高虹镇、横畈镇污水管网工程190万元，临安市饮用水工程555万元，临安市昌化山核桃林地水土流失治理工程232万元，淳安县农村沼气项目171万元等。

Obviously, the nutrient cycles mechanism of Slash Pine is characterized by high nutrient use efficiency with low cycling rate, so in management of Slash Pine plantation, the relation between forest utilization and forest land tending must be dealt with rationally in order to prevent forest land degrading.

可见湿地松具有高养分利用率、低循环速率的循环机理，经营过程中应处理好养地与用地的关系，才能防止林地退化。

Any of various tall perennial grasses of the genus Calamagrostis having feathery plumes; natives of marshland fens and wet woodlands of temperate northern hemisphere.

拂子茅属任何一种多年生高草；原生于北半球温带的沼泽和潮湿林地。

The results showed that there were significant differences among parameters of texture feature of the different land utilization. In the desertification, the mean and variance were comparatively high. The gray level was asymmetry, the contrasts between neighboring pixels were significant; while in water and irrigable land, the mean, variance was a little bit low, the grey level was symmetry; the mean, variance and gray level in the forest and dry land was between the above (desertification and water and irrigable land).

不同土地利用类型之间纹理特征参数差异明显，荒漠化土地的均值、方差值较高，灰度分布不均匀，相邻像元反差明显，内部变化剧烈；水体和灌溉耕地的均值、方差值很低，灰度值均匀，内部变化小；林地和旱耕地信息介于上述两类土地之间。

However, the C and N turnover through by fine root production to the A layer of the soil and belowground is relatively high.

但是，在土壤和林地的A层，细根周转的碳、氮量占有较高的比例。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
